WebUtah has experienced 17 earthquakes greater than magnitude (M) 5.5 since pioneer settlement in 1847, and geologic investigations of our region’s faults indicate a long history of repeated large earthquakes of M 6.5 and greater prior to settlement. Seismic activity can often trigger a succession of additional potentially destructive hazards. WebDivergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow.

WebWhen a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt. WebA single plate is usually rimmed by more than one type of plate margin. Different kinds of plate margins are more or less likely to be associated with particular geologic hazards such as earthquakes and volcanoes, and certain kinds of rocks.

Mantle rock in those extra-hot regions is more buoyant than the surrounding rocks, so it rises through the mantle and crust to erupt at the surface. summary of langston hughes harlem
